Schematic illustration of the BDD measurement based on CBCT results. a, b The analysis of each target tooth was accomplished based on a comprehensive assessment in three layers, including the buccal 1/3, median, and lingual 1/3 layer. c In each layer, the BDD (C) was calculated according to the formula: C = A – B. A represents the distance from the cementoenamel junction (CEJ) to the lowest point of alveolar bone defect; B represents the distance from the CEJ to the vertex of the alveolar crest. The final analyzed BDD of this target tooth was the average of the measured values in three layers (buccal 1/3, median, and lingual 1/3 layer). Figure created with BioRender.com.
